CORRELATIVE ANALYSIS OF NAIL FORM TO TOOTH FORM
Aim: This observational study investigated the correlation of nail form to tooth form.
Materials and Methods: Measurements of the length and width of left maxillary central incisor and the nail of the left hand’s forefinger of 110 subjects were taken with the help of a calibrated manual vernier caliper. The information obtained was statistically analyzed using Pearson’s correlation test.
Results: A positive correlation existed between incisor length and nail length (P = 0.001), and incisor width and nail width (P = 0.001). Consistent relationships were also observed between these measurements.
Conclusion: A definite correlation exists between nail form and anterior tooth form. It can be inferred that nail form can be considered amongst other parameters in determining the anterior tooth form.
